With more than a century treading the boards between them, it’s hard to believe that Chita Rivera and Tommy Tune never worked together before their current concert tour, cheekily titled “Chita & Tune: Just in Time.”

“I can’t tell you where I first met Tommy,” Rivera says. “Our paths crossed as friends but not as performers. Dancers are like a family, and even if we don’t know each other well, we feel as though we do. …

“I think Tommy is quite an extraordinary guy, getting more and more handsome the older he gets.”

The concert will highlight favorite songs from both performers’ careers. For Rivera, that includes the originating roles in “West Side Story,” “Chicago” and “Kiss of the Spider Woman.”

It was “West Side” in 1957, and the role of the outspoken Anita, that made her a star — and also a pioneer. She was a proud Latina in an era when the Great White Way was, well, way white.

So it’s no surprise that Rivera is a fan of “Hamilton,” Lin-Manuel Miranda’s hip-hop musical that features actors of color playing America’s founding fathers.

“I’ve only seen it once, but I definitely want to go back several times,” she says. “I want to go back to see the choreography, because it all blends so magnificently, and I was so bent on hearing every single word. …

“I think Lin-Manuel deserves absolutely everything that he’s getting. He is an extremely gifted guy, a very fine human being, and loves the theater. Loves it.”

Nonetheless, Rivera isn’t necessarily on board with the current generation of actors who are calling for more authentic casting of Latino roles.

“I have played all different nationalities, and I deeply believe that the play is the thing,” she says. “The person who does that role better than anyone else is the person who should get that role, regardless of their background or heritage. It’s the person who does the part the way that the librettist wants it done.”
